Joint beamforming and channel selection for multicast IEEE 802.11n WLANs
(2008)
Multicast transmission over WLANs is becoming a popular application. IEEE 802.11n technology is developed due to the ever increasing demand for higher data rate and Quality of Service (QoS). However, there is an unmanaged ...
Low-complexity beamforming techniques for IEEE 802.11n WLANs
(2009)
The impetus of the present study is to describe a downlink beamforming method that increase spectrum efficiency and significantly reduces implementation complexity and power consumption compare to beamforming technique at ...
Interference mitigation in co-working IEEE 802.11n WLANs
(2009)
In a densely deployed Wireless Local Area Network (WLAN) environment, Access Points (APs) could be so close to cause significant channel interference. In the next generation IEEE 802.11n WLANs, inter-cell interference ...
FIJI: Fighting implicit jamming in 802.11 WLANs
(2009)
The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take ...
LAC: Load-aware channel selection in 802.11 WLANs
(2008)
Dense deployments of hybrid WLANs result in high levels of interference and low end-user throughput. Many frequency allocation mechanisms for WLANs have been proposed by a large body of previous studies. However, none of ...
Contention and traffic load-aware association in IEEE 802.11 WLANs: Algorithms and implementation
(2011)
Efficient association of a station with the appropriate access point has always been a challenging problem. The standard approach of considering only the Received Signal Strength, has recently been substituted by more ...
A demonstration of video over an IEEE 802.11 compliant version of the enhanced-backpressure algorithm
(2012)
This demo presents a novel routing and scheduling scheme, named Enhanced-Backpressure over WiFi (EBoW), that obviously outperforms the dominant approach of a shortest-path routing (SRCR) combined with the classic CSMA/CA ...
Implementation and end-to-end throughput evaluation of an IEEE 802.11 compliant version of the enhanced-backpressure algorithm
(2012)
Extensive work has been done in wireless multihop routing with several ideas based on shortest path or load balancing routing algorithms, that aim at minimizing end-to-end delay or maximizing throughput respectively. ...
Novel metrics and experimentation insights for dynamic frequency selection in wireless LANs
(2011)
The rapidly increasing popularity of IEEE 802.11 WLANs has created unprecedented levels of congestion in the unlicensed frequency bands, especially in densely populated urban areas. Performance experienced by end-users in ...
A demonstration of video over a user centric prioritization scheme for wireless LANs
(2008)
Due to the unreliable nature of the wireless medium, provisioning of the Quality of Service (QoS) in wireless LANs is by far more complicated than in wired networks. In this demo we show the efficiency of a new QoS support ...
